含螺噁嗪光致变色薄膜的全光开关特性

采用旋涂法和滴涂法制备了含螺噁嗪光致变色分子的不同基质薄膜，并将其应用于全光开关实验中.分别对含有螺噁嗪的聚甲基丙烯酸甲酯薄膜和二氧化硅薄膜的光致变色特性进行了吸收光谱的比对研究，结果表明：螺噁嗪/聚甲基丙烯酸甲酯薄膜经过多个开关周期后透射信号强度明显衰减；螺噁嗪/二氧化硅薄膜透射信号强度保持不变，具有更为优异的光学可逆性，更适合于作全光开关.在全息光开关实验中，选用螺噁嗪/二氧化硅薄膜，采用光擦除和热擦除两种方法研究了它的输出光信号衰减动力学特性，发现光擦除具有更短的响应时间.基于光擦除法研究激发光功率为5 mW、10 mW、25 mW时的光开关特性，发现当激发光为10 mW时，光栅对比度、衍射信号强度和开关对比度等特性最佳.

Abstract

The different matrices films containing the photochromic molecules of spirooxazine were prepared by the spin-coating method and the drop-coating method, which were further applied to all-optical switch. The photochromic characteristics of spriooxazine doped polymethyl methacrylate and silicon dioxide films were investigated, and their absorption spectra were compared with each other. The results show that the intensity of the transmitted signal for the spriooxazine doped polymethyl methacrylate film obviously decays after multiple switching cycles, and the intensity of transmission signal for the spriooxazine doped silicon dioxide film keeps constant. Therefore, the latter one has a relatively higher optical-reversibility and is more suitable for all-optical switch. For the spirooxazine doped silicon dioxide film, photo-erasure and thermal-erasure were applied to the experiment of holographic optical switch. Then, the decay kinetics of the output optical signal was investigated. It is found that a shorter response time is obtained in photo-erasure. Based on photo-erasure, the optical switching characteristics of 5 mW, 10 mW and 25 mW were studied. The results show that the optimized power appears at 10 mW, in which the contrast of grating, the first order diffraction light intensity and the contrast radio are all the highest.
